.To aZZ whom it may concern.-

Be it known that 1, DAVID H. COLES, a citizen of the UnitedStates,residing at New York, in the county and State of New York, have 5invented new and useful Improvements in Quilting-Machines, of which thefollowing is a specification.

My invention relates to improvements in quilting-machines; and itconsists in certain i novel features of construction, which are fullypointed out in the following specification and claims and illustrated inthe accompanying; drawings, in which-- Figure 1 is a plan or top view,the parts to the right of the vertical shafts m and a being omitted.Fig. 2 is a horizontal section in the plane :0,Fig. at. Fig. 3is anendview. Fig. 4is vertical section in the plane g y, Fig. 2. Fig. 5 is avertical section in the plane z 2, Fig. 1, the rollers E F and I. Jbeing shown in section. Fig. 6 is a vertical section in the plane .v 00,Fig. 1. Figs. 7 to 18 are details, which will be described as thespecification progresses.

Similar letters indicate corresponding parts.

In the drawings, thelet-ter A-designates the frame, and to it aresecured the guides a, for the needle-bars b, to which the necessaryupand-down motion is eommunicat ed by the arms 0, mounted on a shaft, B,running through the 0 whole length of the machine and having itshearings in the frame A. On one end of this shaft is secured an arm, (1,Figs. 1 and 6,which is connected by rods e f and bell-crank lever g withan eccentric, 72, mounted on the shaft 0, Figs. 2 and G. This shaftisintermittently rotated, as will hereinafter be described. The shaft 0also carries an eccentric, 2', Figs. 2 and 5, which is connected by arod,j, with an arm, is, secured to the rock-shaft D, on which aremounted a series of arms, Z, which are connected to the shuttle-carriersm by links at. When the shaft 0 is rotated, the desired reciprocatingmotion is given to the shuttle-carriers, causing them .to slide in theguides 0, 5 Fig. 5, which are secured to the frame A.

I do not desire to confine myself to this construction of needle andshuttle operating devices, as any other suitable devices may be applied,and an intermittent motion be im- 5o parted to them.

Serial No. 181,286. (No model.)

The machine shown in the drawings contains all the appliances fortufting, and will turn out tufted quilts of the pattern indicated inFig. 17,in which the tufts are quincuncially placed; but this patternmay be essentially varied, by any skilled operator. To produce thispattern itis necessary, first,to introduce the quilting and tu ftingmaterial under the needle. Second, to give the quilting and tuftingmaterial together the necessary feed motion, so 6 that the operationofthe sewing device will cause the needle to stitchthrough both thedesired number of times and then stop. This feed motion I term theprimary feed. Third, the whole must then be fed forward to form 6 thedesired length of tuft. Fourth, the tuft must then be cut off by thecutting device. Fifth, the quilting material alone must then be fedforward and sideward independent of the stitch-forming mechanism and theprimary feed, until the place for a new tuft comes under the needle,when the whole operation is re peated by the continued action of themachine. This operation and the third operation are accomplished bymeans of the mechanism which 7 1 herein refer to as independentcloth-feed mechanism.

I will now proceed to describe these operations in their order and indetail.

7 First. The quilting material, which gener- 8o ally consists of twothicknesses of cloth, with a layer. of cotton-batting between them, isfirst passed between the feed-rollers E and F, then between the upperfeed-bar, G, and the under feed-bar, H, and then under the feed- 8roller J, and between the same and the feed roller I. The rollers I andJ have their bearings in standards F, which can be adjusted by means ofthe screws F". This adjustment is necessary to properly control theoperation 0 of these rollers. The tufting material may consist of one ormore strands of cord, yarn, or strips of cloth, and is wound on spoolsK, which turn on a rod, 1), loosely placed in hangers,'q, secured to theframe of themachine. It then passes through guides r,which project fromthe hangers, and then through openings 8, Fig. 7, in the upper feed-bar,G, which brings it directly under the needle. Both the quilting and thetufting material'are 100 then grasped between the feed-bars G and H.These feed-bars run the whole length of the machine, and while both movein a horizontal plane. the upper one, G, also moves vertically, and thisvertical motion is controlled in one direction by springs 16, Fig. 8,and in the other by the feed-bar-lifting mechanism,which will bepresently described. Said upper feed- Lar, G, is provided at each endwith a hub, a, from which project lugs aagainst which press verticalrods 10, having bearings a',Figs. 2 and 4, in the frame A, and subjectto the action of levers b, which are pivoted at c and rest on cams d,mounted on the main shaft L. As the latter revolves, the feed-bar G israised by means of the cams d, the levers b, and rods w, and depressedby the springs t,which will cause the same to grasp the work, as abovedescribed.

Second. The tufting material is firmly held against the quiltingmaterial between the feedbars and directly under the needle, as abovedescribed. The feed-bars, together with both materials,are now caused tomove horizontally in a closed curve by a step-by-step motion, while thesewing mechanism also operates and the needle descends and stitchesthrough both materials, producing asmall circleor polygon of stitches,(see Fig. 16,) which pass through and serve to hold together bothmaterials. \Vhen this has been accomplished,both the primary feed andthe sewing mechanism stop. This intermittent circular or polygonalfeeding and sewing is produced as follows: On the outer end of the mainshaft L is mounted a mutilated gear-wheel, M, which engages a pinion, N,secured to one end of a short shaft, 6, which has its bearingsin theframe A,and the other end of which carries a cog-wheel, f, which meshesinto the pinion O on the shaft C, Figs. 2, 3, and 4. In the exampleshown in the drawings these gears are of such proportions to each otherthat the shaft 1, from which the parts necessary to the second operationreceive their motion, makes twelve revolutions for every revolution ofthe mutilated gear-wheel M, carried by the main shaft L; or, in otherwords, the teeth remaining on said mutilated gear-wheel are sufficientto cause the shaft 0 to make twelve revolutions, after which the saidshaft stands still during that part of the revolution of the mutilatedgear in which the blank space comes opposite to the pinion N. To controlthelastdescribed operation positively,and to prevent the motion of anyof these parts during the time when the blank space passes the pinion N,a flange, g, is formed, Figs. 2 and 3, on the outer side of said pinion,and from it projects an eccentric pin, h, carrying an anti-frictionroller. Vhen the pinion N has reached the end of the toothed portion ofthe gear-wheel M, this eccentric pin it will be opposite the opening ofa cam-groove, 1, formed in the side of the mutilated gear-wheel, and asthe latter revolves the cam-groove will pass over said eccentric pin h,thereby preventing the pinion N and all parts connected with it fromturning until the toothed portion of the gear M is again reached,whenthe cam-groove will release the eccentric pin h, and the pinion N willagain be free to turn, subject to the action of the teeth on themutilated gear M. On the shaft 0 is mounted a cam, Q, Figs. 2 and 5,which acts on an anti-friction roller, i, secured to one end of alever,j, turning on a pivot, it, while the other end of the lever j connectsby a rod, 1, with a dog, on, on the stud a, and carrying a pawl, 0,which engages a ratchetwheel, 1), secured to a cog wheel, g, whichmeshes into a pinion, r, mounted on the shaft B, Fig. 5. This shaft,which has its bearings injournals s, secured to the frame, carries abevel gear, t, Figs. 4 and 6, at each end, which mesh into similargears, a, mounted on the upright shafts '0, having bearings 10 in theframe, and carrying at their upper end disks a To these disks aresecured other disks, b", by means of bolts 0", Fig. 15, passing throughslots (1 From the disks If project upright eccentric pins 0 which passfirst through the hubs f at each end of the lower feed-bar, H, Figs. 8and 14, and then through the hubs a at each end of the upper feed-bar,G, Fig. 8, so that when the upright shafts o, to which the eccentricpins 0 are attached, are rotated both the upper and lower feed-bars andthe work which is held between them are carried around in a curvesimilar to the one traveled by the upright eccentric pins 0. Aspreviously described, each revolution of the main shaft will cause theneedle to descend twelve timesthat is, the sewing mechanism will maketwelve stitches, which, by the peculiar motion given to the work by thefeed-bar,will fall in a circle. To form a complete circle of twelvestitches it will be necessary that the feed-bars be carried around inthe said circle in eleven steps or feed motions, so that when the needledescends the twelfth time it will strike the spot at which itstarted andcomplete the circle. In other words, to make a circle or polygon ofstitches it is necessary to make one more stitch than there are feedmotions. This is accomplished as follows: The shaft 0, which actuatesthe stitch mechanism, is geared to a shaft, 0, in such a manner that thelatter will make one revolution less than the former for everyrevolution of the main shaft L. In this example the shaft 0 makes twelverevolutions,while the shaft C will make only eleven. The shaft 0 carriesthe cam Q, and each revolution of this cam will turn the lever j on itspivot against the action of the spring 9', Fig. 5, and will cause theratchet-wheel, which has eleven teeth, to be moved forward one tooth, sothat when the shaft Ohas made the eleven revolutions described above theratchet-wheel p and the cog-wheel attached to it will have made onecomplete revolution,while the shaft R, which carries the pinion r,'whichhas only half as many teeth as the cog-wheel q, will have made tworevolutions, thus causing the upright shaft 2) to make two revolutionsalso,

and to feed twice around the circle described by the eccentric pins e Toobviate any liability of breaking the thread as the work is fed aroundthe second time, by the needle again passing down through one of thestitches made before, I cut an odd number say eleven-teeth in theratchet wheel 1;, which will insure the passage of the needle through anew place in the work at each stitch, and

make a polygon of stitches. (Shownin Fig. 16 three times natural size.)In the machine shown the curves made by the eccentric pin c are ofa verysmall diameter just large enough to securely sew on thetufting; but itis evident that they may be increased to any size and the work quiltedin a number ofpatterns without tufting. For instance, a pattern like 7Fig. 18 could be produced without any essential change in the mechanism.

Third operation-fecding the work forward to make length of tuft: Afterthe second operation the relative position of the work and the feed-barswill be as shown in Fig. 9 that is, the tufting material will be sewedonto the quilting material near the end of the former, and the needlewill be in its upper position, while the work will still be graspedbetween the feed-bars. It is now necessary to feed the work forward thedesired distance, so as to bring the tufting material under the cuttingdevice in such a position that when the latter operates, which will bethe next operation, it will cut a tuft of proper length. To admit of thenecessary forward feed, the upper feed-bar must first be raised to itsupper position, so as to release the work, while the cutting device,which is loosely attached to this feed bar, must also be raised topermit the free motion of the work. The raising of the upper feed -baris accomplished as described in the first operation by the cam d,mounted on the main shaft L, while the cutting device is raised. by asomewhat similar cam, a", Fig. (3, mounted on the same shaft and actingon a lever, v", on which rests the rod 10*, abutting against a lug, a,on the cutting device. This cam is of such a shape that it will raisethe cutting device just clear of the work during this operation and intoproper position for action, which will form the next operation. Thework, as has been described, is held between the feed-rollers I J, whichare caused to move together by llangd gears It, and are intermittentlyrotated by a pawl, i Figs. 1 and (5, acting on the ratchet-wheel j Thisratchet-wheel is secured to a cog-wheel, It, which turns loosely on astud, Z, projecting from the frame, and meshes into a pinion, m, mountedon the trunnion n of the roller J. On the main shaft L is mounted a cam,0, Figs.'2 and 5, which acts on an arnnp secured to a shaft, (1 whichalso carries the arm 0, Fig. 6, and the latter is connected by a rod, 8to a dog, i carrying the pawl The cam 0 is so shaped that during thisoperation it will cause the work to be moved forward only sufficient toform a tuft of proper length. The

effect of its further rotation will be described in another operation.At the end of the third operation the relative position of the work, thefeed-bars, and the cutting device will be as shown in Fig. 10.

Fourth operationcutting off the tuft: To the back of the upper'feedbar,which is L- shaped. are 'loosely attached the cutting-bar S and theguide-bar T, and the whole is held together by the action of the spring1), whose pressure may be regulated by the nuts 0 screwed on bolts (1which projectfrom the upper feed'bar. (See Fig. 7.) The cuttingbar andthe guide-bar are also connected to each other in a like manner byspring-bolts 6 By reference to Figs. 7, 12, and 13 it will be understoodthat while the horizontal motion of the feed-bar is also shared by thecuttingbar and the guide-bar, the feed-bar may be moved verticallyindependently of the others, and vice-versa. In one end of thecutting-bar S is a notclnf, Fig. 8, which embraces the upper roundedend, 9, of a lever. U. This notch is of such a shape that when thecuttingbar is down in the position shown in full lines in Fig 8 and inFig. 9 it will permit the horizontal motion of the cuttingbarasit iscarried around with the upper feedbar, but when raised to the positionfor cutting (shown in dotted lines in Fig. 8 and in Fig. 10) the sidesof the notch f will closely embrace the upper roundedend g of the leverU, and the cuttingbar will move laterally when this lever, which ispivoted at 71 is acted on by the grooved cam 1' mounted on the mainshaft L, Fig. 2. When the work has been fed forward sufii ciently toform the tuft, as described in the previous operation, and the feed andcutting bars have been properly raised, the tufting material will restin the cutting-notches j,

formed in the lower edge of the cutting-ban Fig. 13, and also in thenotches ldof the guidebarT. (SeeFigs.10,12, and 13.) Thegrooved cam ithen acts on the cutting-bar, moving the same lateral] yin the directionof the arrow marked on it in Fl 8, while the feed and guide bars remainstationary, thereby shearing off the tufting material and finishing thetuft.

Fifth operationfeeding the quilting material forwardand sideward untilthe place for a new tuft comes under the needle: After the cuttingoperation has been completed, the cam it raises the cutting and guidebars intothe position shown in Fig. 11, and the quiltingmaterial is nowfree to move, subject to the action of the feed-rollers E F and I J. Thelatter now receive a simultaneous lateral and revolving motion. Therevolving motion is caused by the cam 0 which must be of such shape orconfiguration that while revolving it will effect the motions predicatedto it. The quilting material is thus caused to be fed forward, while thesideward motion of the feedrollers is imparted to them by a forked arm,Z Figs. 1 and 4-, mounted 011 the upper end of an upright shaft, mhaving its bearings a IIO in the frame A. The lower end of this shaftcarries a lever, 0 Fig. 2, one end of which is toothed and engages atoothed segment, 19 on the end of a shaft, (1 having its bearings r inthe frame, and which receives a slightly-rotating motion by the actionof the grooved cam engages a grooved collar, J, on the trunniong of thefeed-roller F, Figs. 1 and 4. The feed-rollers E and F are connected byflanged gears h 6, Figs. 1 and 6.

When the last operation has been completed and the quilting material hasreached the position for a new tuft, the upper feed-bar willagaindescend, clamping the tufting material onto the quilting material,and the five operations above described will be renewed.
